Since 1978, productivity in the nonfarm business sector is up 86% but real compensation per hour is up just 37%. Is that fair?

That's the question economist Alan Blinder asked in his Friday column in the Wall Street Journal. There are two levels to the conundrum: (1) Why is this happening and (2) What, if anything, should government do to fix it?

Let's turn to the first question: If the US worker is making more stuff in less time, where is that productivity going if it's not going to higher wages? For the answer, look at manufacturing. Our industrial production has grown by a factor of five since the 1950s (graph below). Over the same period, manufacturing jobs as a share of the economy have fallen from 25% to 11% in 2008. The difference is machines. Technology helps companies make more stuff, faster, for less money. It also replaces the need for workers. So in the last few decades, manufacturing has learned to produce much more stuff with fewer humans.

Technology isn't the only disruptive force. Outsourcing, which started to take off in the early 1990s, targeted low-level white collar jobs in IT infrastructure, customer service and software, sending millions of jobs overseas while holding down their wages at home. The decline of US labor unions further depressed median wages. The inexorable rise in health care costs stole, and steals, raises from average Americans when bosses put more money into untaxed health care premiums and less into taxed earned income. More controversially, you could say that the rise of a CEO Culture has only recently elevated quarterly earnings over hiring considerations, which concentrates corporate earnings in the corner office rather than the cubicles.

The last three decades have worked the US labor force like a centrifuge, spinning jobs away from the middle and toward the top and bottom

So where is the productivity going? More goods, lower prices, richer C-suites, more expensive health care -- but not into paychecks.

How do we fix this? Well, first let's think about what we can fix. We can't unmake the machines that do the work of a dozen 1940s-era manufacturers, nor would we want to. We can't control health care costs without major reforms in both doctor's offices and the US tax code. But perhaps we can create new industries that fill the middle-class vacuum left by the decline in manufacturing employment.

If manufacturing lost 15% of its share of the labor force in the last few decades, where did the jobs go? Three places, basically: (1) finance and real estate; (2) professional and business services; and (3) the health care/education/social services sector. Some of these jobs -- bankers and consultants and doctors -- require many years of post-secondary education, and they pay very well. But some of these jobs -- like personal services and food prep -- don't require much education and don't pay very well. Here's what the hollowing out of the middle class looks like: jobs at the top, jobs at the bottom, and a valley in the middle.

and toward the top and bottom.

What can we do about this at the government level? You can fix the pay gap directly by taxing the wealthy and redistributing their income to the middle and lower classes in the form of earned income tax credits, child credits, lower tax rates, and better public services. Or you can guide the economy to create new industries with more opportunities for the middle class -- by either investing in research and development where we see the potential for growth (green energy, biosciences, etc), or by investing in college education in the hopes that a smarter workforce will research and develop its own ideas.

There is no easy silver bullet to exterminate the myriad causes of this 30-year middle class wage freeze. Those who see US income inequality as a matter of ethics and fairness are more likely to advocate for the short direct route of higher taxes at the top for higher spending for the bottom.

Writing used to be a solitary profession. How did it become so interminably social?

Whether we’re behind the podium or awaiting our turn, numbing our bottoms on the chill of metal foldout chairs or trying to work some life into our terror-stricken tongues, we introverts feel the pain of the public performance. This is because there are requirements to being a writer. Other than being a writer, I mean. Firstly, there’s the need to become part of the writing “community”, which compels every writer who craves self respect and success to attend community events, help to organize them, buzz over them, and—despite blitzed nerves and staggering bowels—present and perform at them. We get through it. We bully ourselves into it. We dose ourselves with beta blockers. We drink. We become our own worst enemies for a night of validation and participation.

Even when a dentist kills an adored lion, and everyone is furious, there’s loftier righteousness to be had.

Now is the point in the story of Cecil the lion—amid non-stop news coverage and passionate social-media advocacy—when people get tired of hearing about Cecil the lion. Even if they hesitate to say it.

But Cecil fatigue is only going to get worse. On Friday morning, Zimbabwe’s environment minister, Oppah Muchinguri, called for the extradition of the man who killed him, the Minnesota dentist Walter Palmer. Muchinguri would like Palmer to be “held accountable for his illegal action”—paying a reported $50,000 to kill Cecil with an arrow after luring him away from protected land. And she’s far from alone in demanding accountability. This week, the Internet has served as a bastion of judgment and vigilante justice—just like usual, except that this was a perfect storm directed at a single person. It might be called an outrage singularity.

Forget credit hours—in a quest to cut costs, universities are simply asking students to prove their mastery of a subject.

MANCHESTER, Mich.—Had Daniella Kippnick followed in the footsteps of the hundreds of millions of students who have earned university degrees in the past millennium, she might be slumping in a lecture hall somewhere while a professor droned. But Kippnick has no course lectures. She has no courses to attend at all. No classroom, no college quad, no grades. Her university has no deadlines or tenure-track professors.

Instead, Kippnick makes her way through different subject matters on the way to a bachelor’s in accounting. When she feels she’s mastered a certain subject, she takes a test at home, where a proctor watches her from afar by monitoring her computer and watching her over a video feed. If she proves she’s competent—by getting the equivalent of a B—she passes and moves on to the next subject.

There’s no way this man could be president, right? Just look at him: rumpled and scowling, bald pate topped by an entropic nimbus of white hair. Just listen to him: ranting, in his gravelly Brooklyn accent, about socialism. Socialism!

And yet here we are: In the biggest surprise of the race for the Democratic presidential nomination, this thoroughly implausible man, Bernie Sanders, is a sensation.

He is drawing enormous crowds—11,000 in Phoenix, 8,000 in Dallas, 2,500 in Council Bluffs, Iowa—the largest turnout of any candidate from any party in the first-to-vote primary state. He has raised $15 million in mostly small donations, to Hillary Clinton’s $45 million—and unlike her, he did it without holding a single fundraiser. Shocking the political establishment, it is Sanders—not Martin O’Malley, the fresh-faced former two-term governor of Maryland; not Joe Biden, the sitting vice president—to whom discontented Democratic voters looking for an alternative to Clinton have turned.

An attack on an American-funded military group epitomizes the Obama Administration’s logistical and strategic failures in the war-torn country.

Last week, the U.S. finally received some good news in Syria:.After months of prevarication, Turkey announced that the American military could launch airstrikes against Islamic State positions in Syria from its base in Incirlik. The development signaled that Turkey, a regional power, had at last agreed to join the fight against ISIS.

The announcement provided a dose of optimism in a conflict that has, in the last four years, killed over 200,000 and displaced millions more. Days later, however, the positive momentum screeched to a halt. Earlier this week, fighters from the al-Nusra Front, an Islamist group aligned with al-Qaeda, reportedly captured the commander of Division 30, a Syrian militia that receives U.S. funding and logistical support, in the countryside north of Aleppo. On Friday, the offensive escalated: Al-Nusra fighters attacked Division 30 headquarters, killing five and capturing others. According to Agence France Presse, the purpose of the attack was to obtain sophisticated weapons provided by the Americans.

During the multi-country press tour for Mission Impossible: Rogue Nation, not even Jon Stewart has dared ask Tom Cruise about Scientology.

During the media blitz for Mission Impossible: Rogue Nation over the past two weeks, Tom Cruise has seemingly been everywhere. In London, he participated in a live interview at the British Film Institute with the presenter Alex Zane, the movie’s director, Christopher McQuarrie, and a handful of his fellow cast members. In New York, he faced off with Jimmy Fallon in a lip-sync battle on The Tonight Show and attended the Monday night premiere in Times Square. And, on Tuesday afternoon, the actor recorded an appearance on The Daily Show With Jon Stewart, where he discussed his exercise regimen, the importance of a healthy diet, and how he still has all his own hair at 53.

Stewart, who during his career has won two Peabody Awards for public service and the Orwell Award for “distinguished contribution to honesty and clarity in public language,” represented the most challenging interviewer Cruise has faced on the tour, during a challenging year for the actor. In April, HBO broadcast Alex Gibney’s documentary Going Clear, a film based on the book of the same title by Lawrence Wright exploring the Church of Scientology, of which Cruise is a high-profile member. The movie alleges, among other things, that the actor personally profited from slave labor (church members who were paid 40 cents an hour to outfit the star’s airplane hangar and motorcycle), and that his former girlfriend, the actress Nazanin Boniadi, was punished by the Church by being forced to do menial work after telling a friend about her relationship troubles with Cruise. For Cruise “not to address the allegations of abuse,” Gibney said in January, “seems to me palpably irresponsible.” But in The Daily Show interview, as with all of Cruise’s other appearances, Scientology wasn’t mentioned.

Some say the so-called sharing economy has gotten away from its central premise—sharing.

This past March, in an up-and-coming neighborhood of Portland, Maine, a group of residents rented a warehouse and opened a tool-lending library. The idea was to give locals access to everyday but expensive garage, kitchen, and landscaping tools—such as chainsaws, lawnmowers, wheelbarrows, a giant cider press, and soap molds—to save unnecessary expense as well as clutter in closets and tool sheds.

The residents had been inspired by similar tool-lending libraries across the country—in Columbus, Ohio; in Seattle, Washington; in Portland, Oregon. The ethos made sense to the Mainers. “We all have day jobs working to make a more sustainable world,” says Hazel Onsrud, one of the Maine Tool Library’s founders, who works in renewable energy. “I do not want to buy all of that stuff.”

The Islamic State is no mere collection of psychopaths. It is a religious group with carefully considered beliefs, among them that it is a key agent of the coming apocalypse. Here’s what that means for its strategy—and for how to stop it.

What is the Islamic State?

Where did it come from, and what are its intentions? The simplicity of these questions can be deceiving, and few Western leaders seem to know the answers. In December, The New York Times published confidential comments by Major General Michael K. Nagata, the Special Operations commander for the United States in the Middle East, admitting that he had hardly begun figuring out the Islamic State’s appeal. “We have not defeated the idea,” he said. “We do not even understand the idea.” In the past year, President Obama has referred to the Islamic State, variously, as “not Islamic” and as al-Qaeda’s “jayvee team,” statements that reflected confusion about the group, and may have contributed to significant strategic errors.

The new version of Apple’s signature media software is a mess. What are people with large MP3 libraries to do?

When the developer Erik Kemp designed the first metadata system for MP3s in 1996, he provided only three options for attaching text to the music. Every audio file could be labeled with only an artist, song name, and album title.

Kemp’s system has since been augmented and improved upon, but never replaced. Which makes sense: Like the web itself, his schema was shipped, good enough,and an improvement on the vacuum which preceded it. Those three big tags, as they’re called, work well with pop and rock written between 1960 and 1995. This didn’t prevent rampant mislabeling in the early days of the web, though, as anyone who remembers Napster can tell you. His system stumbles even more, though, when it needs to capture hip hop’s tradition of guest MCs or jazz’s vibrant culture of studio musicianship.

Jim Gilmore joins the race, and the Republican field jockeys for spots in the August 6 debate in Cleveland.

After decades as the butt of countless jokes, it’s Cleveland’s turn to laugh: Seldom have so many powerful people been so desperate to get to the Forest City. There’s one week until the Republican Party’s first primary debate of the cycle on August 6, and now there’s a mad dash to get into the top 10 and qualify for the main event.

With former Virginia Governor Jim Gilmore filing papers to run for president on July 29, there are now 17 “major” candidates vying for the GOP nomination, though that’s an awfully imprecise descriptor. It takes in candidates with lengthy experience and a good chance at the White House, like Scott Walker and Jeb Bush; at least one person who is polling well but is manifestly unserious, namely Donald Trump; and people with long experience but no chance at the White House, like Gilmore. Yet it also excludes other people with long experience but no chance at the White House, such as former IRS Commissioner Mark Everson.
